Descrição: We demonstrate that, under specific experimental conditions (isothermal crystallization from a single nucleation event in nearly spherical specimens), differential scanning calorimetry data can be used to deduce the velocity of a crystallization front in undercooled liquids. For Pd43.2Cu28Ni8.8P20 alloy and 683K < T < 700K, the growth velocity is ~4.3 x 1013 (m s-1) exp (-2.7 eV/kT).
